Singlespeed & Fixed Gear "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer? We are getting soft...As for me, give me a fixed gear!"-- Henri Desgrange (31 January 1865 - 16 August 1940)

Disc I need more threading, chain line issues

Hi Guys, here is concise breakdown

I am using a road TT frame for track pursuit event. I have a Zipp 900 rear disc with a long track axel so it fits the 130mm horizontal drop outs of the TT bike.

However, my problem is that the threading on the axel for the Cog is shallow, as a result the chain line is off a bit. Is there an adapter that can screw on to the existing threading to extend it. If I can just get a little more threading to move the Cog to the right, it will line up perfectly.

Thanks

As strange as this may sound, I think you will have luck asking in the SSFG forum. This comes up a lot on that scene.

How old is this disc? I've used the 900 before. One way to tell is if the stickers are removable. If they are it's an older model, if they aren't it's a newer model.
